Application filed September 11, 1915. Serial No. 50,238.

To all whom it may concern; Be it known that 'I, FRANK B. MoCAnn, a citizen of the United States, residing at Lewiston, in the county of Mifliinand State of Pennsylvania, have invented a new and useful Rock-Crusher, of'which the following is a specification.

The present invention appertains to rock and stone crushers, and aimsto provide a novel and improved machine of that nature embodying unique means formounting the crushing jaws whereby they are given such movements as to effectively crush the rock or stone.

With the foregoing and other objects in view which will appear as the description proceeds, the invent-ion resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be'made within the scope of what is. claimed without departing from the spirit of the invention. The invention is illustrated inthe accompanying drawings, wherein:.

Figure 1 is a plan view of the improved crushing machine. Fig. 2 is a side elevation thereof. Fig. 3 is a longitudinal sec tion taken on the line 33 of Fig. 1. Fig. .4 is a transverse section taken on the line H of Fig. '1, portions being broken away, and this view being onan enlarged scale. In carrying out the invention, there is provided a frameembodying upright sides or side sections 1, preferably in the form of castings, andset on edge, the ends of the sides or sections 1 having angularly extending portions 2 abutting .againstone another to provide the ends of the frame. The portions 2 are provided with outstanding abut ting ears 3 through which bolts 4: are engaged for clamping the sections together rigidly. 1

The sections 1 are provided between their ends and adjacent their loweredges with hearings or seats5 and with openings 6 above said bearings,.and caps 7 arexbolted orotherwise secured upon the bearings ,5. A

transverse driving shaft 8 is journale'd through the bearings 5 and their caps 7.,and

the drivingshaft 8 carries a pulley wheel 9 at one side of the frame over which a belt may be passed for purpose of rotating the driving shaft, although it is to be understood that the driving shaft may be rotated also provided adjacent their ends andtheir upper edges with bearings or seats 10 upon which caps 11 are bolted or otherwise secured, and a pairof transverse shafts 12 are journaled through the bearings 10 and their caps 11 adjacent the, ends of the frame. The drivingshaft 8 is located in a horizontal plane below the horizontal plane in which the shafts 12 are located, and the shaft 8 is located in a vertical, plane between the vertical planes in which the shafts 12 lie. Sprocket wheels 13 and 14 are secured to the shafts 8 and 12, respectively, at the opposite sides of the frame, whereby the shafts 12 in any suitable manner. The sections 1 are are operatively connected with the shaft 8 to be driven thereby, sprocket chains 15 being trained around the respective pairs of sprocket wheels 13 l4.

The shafts 12 are provided with eccentrics 16 between the bearings 10, and the eccentrics are embraced by the remote ends of a pair of relatively long crushing jaws 17 which project horizontally toward one an other" within the frame in approximate alinement. 17 have seats 18 for receiving the eccentrics 16, and caps 19 'are bolted or otherwise fastened to the body portions of the jaws to cooperate with the seats 18 for embracing the eccentrics. centrics 16 serves tov give the remote ends of the pawl a crank motion.

In order to mount the jaws for peculiar motionwithin the frame, lower and upper The body portions of the jaws The rotation of the ectransverse pins 20 and 21, respectively, are I engaged through suitablebores provided in the jaws near their adjacent ends. The pro truding ends of the lower pins 20 work within the inclined slots 22 of plates 23 secured to the outer sides of the sections 1, 1

Thesections 1 are of course slotted to corre clined slightly from vertical lines, so that the slots 24 will be referred to as being vertical for sake of convenience. The pins 2021 working in the respective slots 222 L give the adjacent ends of the jaws peculiar motions as will hereinafter more fully apear. P The adjacent ends of the jaws 17 are provided with lower'vertical faces 26 covered by face plates 27 having cooperating transverse or horizontal corrugations 28. The plates 27 have vertical dove-tailed tongues 29 dropped in vertical dove-tailed grooves or recesses 30 with which the adjacent ends of the jaws 17 are provided. The adjacent ends of the jaws also have upper inclined faces 31 diverging upwardly from the faces 26, and covered by face plates 32 which have vertical corrugations 33.- The plates 32, like the plates 27 have vertical dove-tailed tongues 34 dropped or fittedin vertical dovetailed grooves or recesses 35 with which the adjacent ends of the aws are provided, the recesses 35 as well as the recesses 30 opening upwardly and having their lower ends closed. 'The plates 27 are applied to the jaws before the plates 32, in assembling the parts and the plates 32 rest upon and hold the plates 27 in place.

In order to pull the jaws 17 against the eccentrics 16, rods 36'have their adjacent ends threadedly engaging the lower portions of the adjacent ends of the jaws, and the rods 36 are slidable through the'ends' of the frame, coiled wire eXpansion springs 37 being disposed between the ends of the frame and nuts or heads 38 secured upon the re-' mote ends of the rods 36. The springs 37 surrounding said rods. The springs 37 in expandingwill pull the rods 36 outwardly, to thereby move the jaws 17 against the eccentrics'lfi, so'as toeliminate loose play.

In operation, the stone or rock to be crushed is dropped in any suitable manner between the inclined or diverging face plates 32 of the jaws, and when the eccentrics are rotated, the jaws are operated for purpose of crushing the rock 'orstone. 'When the eccentrics move inwardly, they force the jaws 17 toward one another, and the lower pins 30 working in the inclined slots 22' will cause the adjacent ends of the jaws to move downwardly when saidends are moved toward one another, the upper pins 21 moving downwardly in the upper slots 24. Thus,

I when the face plates are moved toward one another, they are also moved downwardly, resulting in the efiective crushing of the rock or stone. When the eccentrics move outwardly, they pull the jaws 17 away from one another, that is, without the assistance of the springs 37 and when said springs are used, they pull the jaws apart when the eccentrics 16 move outwardly. When the jaws are moved away from one another, the adjacent ends thereof are also raised due to the pins 20 and 21 working in the respective slots of the frame. I V

The rock or stone will be gradually crushed between the inclined upwardly diverging face plates 32 as the rock or stone works downwardly between said face plates, and the final crushing .of the rock or stone is accomplished between the vertical face plates 27 which crush the stone or rock to the desired fineness. Attention is directed to the fact that the corrugations 33 of the upper face plates 32 are arranged vertically whereby the rock or stone can work downwardly within said corrugations duringthe movement of the jaws, while the corrugations 28 of the lower face plates 27 aredisposed horizontally for effectively finishing the crushing of the rock or stone. 1

Due to the fact that the aws are operated by the eccentrics, and have the pins work ing in the slots of the frame, the adjacent or active endsof the jaws are given the several motions to enhance the efficiency of themachine incrushing the stone or rock. 7 By arranging the plates 23-25 in various positions, the'movement of the adjacent ends of the jaws can be adjusted ac cordingly, andit is thus possible to control and regulate the movements of the jaws according to the nature of work to bedone.

Having thus described the invention, what is claimed as'new V r V 1. In a crusher, a relatively long horizontal jaw, a second jaw cooperable with one end thereof, means for actuating the other end of the first mentioned jaw for moving said jaw to and from the second mentioned jaw, and means for. mo-ving the first mentioned end of the first mentioned jaw bodily the second mentioned jaw.

2. In a crusher, a pair of relatively long horizontal :jawspro ecting toward one another in' approximate alinement, means for actuating the :remote ends'of the jaws for downward when said jaw is moved toward moving them toward and away from one another, and means for moving the adjacent ends of the-jaws bodily downward when the are moved toward one another. 1

3. In a crusher, a frame, a relatively long horizontal jaw therein, a second jaw carried by the frame cooperable with one end of the aforesaid jaw, and means for actuating the other end of the first mentioned jaw to move it to and from the second mentioned jaw, the first mentioned end of the jaw and 1 moved 4. In a crusher, a frame, a pair of relatively long horizontal jaws in the frame arranged in approximate alinement, the frame including inclined slots, and the adjacent ends of the jaws having pins working in said slots, and eccentrics carried by the frame for rotation, the remote ends of said jaws having portions embracing said eccentrics, the pins working in said slots to move the adjacent ends of the jaws downwardly when 1 the jaws are moved toward one another.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
